People have already been up in arms over the rust issue at the newly built Barclays Center in Brooklyn, but there was another issue in the facade as well: weak bolts! The Department of Buildings reports thousands of the bolts (8% to be exact) used to hold together the 12,000 unique panels were a weaker type of bolt than should have been used, and they had to be replaced.

The issue was discovered a month before the opening of the grand arena, but the issue wasn’t fixed until just last month. The construction company involved has played down the problem, saying such issues are common in large construction projects. As long as it’s fixed now, that’s all that really matters!
